What is point point control?
The point-to-point (PTP) control system is many times referred to as the positioning system. The primary function of the PTP control system is to move a tool from one point location to another specified point, generally to do hole operations such as drilling, boring, reaming, tapping and punching.
What is continuous path control?
Continuous Path Control System. A continuous path control system is one in which the robot is programmed to follow an irregular path exactly. Inside the control system, the path to be travelled is represented by a large number of points in close proximity; these points are stored in the robot’s memory.
Which is the operation in point to point system used?
Explanation: Such systems are used, typically, to perform hole operations such as drilling, boring, reaming, tapping and punching. In a PTP system, the path of the cutting tool and its feed rate while traveling from one point to the next are not significant, since, the tool is not cutting while there is motion.
When the contour or continuous path system is used?
Continuous-path NC systems are commonly used on machines that perform contouring operations, such as milling machines, lathes, flame-cutting machines, and drafting machines. Program preparation for continuous-path machines is more complex and usually requires the aid of a computer.
Is the heart of CNC system?
MCU or Machine Control Unit is the heart of a CNC system actually. It involves several actions to perform in a CNC machine.
Which are examples of PTP CNC operation?
NC drill presses are a good example of PTP systems. The spindle must first be positioned at a particular location on the workpiece. This is done under PTP control. Then the drilling of the hole is performed at the location, and so forth.
Which is a example of straight cut CNC machine?
An example of a straight-cut operation is shown in Figure 8.6. An NC machine tool capable of performing straight-cut movements is also capable of point to point movements. Contouring is the most complex, the most flexible, and the most expensive type of machine tool control.
Which axis is used in CNC lathe?
In CNC lathe machines, the parallel direction of the spindle is Z axis. The head direction is negative (-Z), and the direction perpendicular to Z axis is X and Y directions. You can use the thumb of the left hand (X axis), the index finger (Y axis), and the middle finger (Z axis) to become three axes.
What is the function of the driving system in CNC?
Basic function of a CNC machine is to provide automatic and precise motion control to its elements such work table, tool spindle etc. Drives are used to provide such kinds of controlled motion to the elements of a CNC machine tool. A drive system consists of drive motors and ball lead-screws.
What are the basic components of CNC system?
Components of a CNC system
- Central processing unit (CPU)
- Input devices.
- Machine control panel.

What is the control system of the CNC machine?
A CNC system requires motor drives to control both the position and the velocity of machine axes. There are two ways to activate the servo drives; the open-loop system and the closed-loop system. In an open-loop CNC system, programmed instructions are fed into the controller through an input device.
What’s CNC sexually?

Hands down absolutely the best Chinese CNC router on the list. All the machines produced by OMNICNC are good and crafted in way that they require the minimum bit of maintenance. However, these are very efficient machines and can effectively cut through a huge number of materials without getting tired or damaged.
Are CNC routers worth it?
They are hugely efficient at cutting curves accurately. But they are not so efficient at cutting square/rectangular parts. You’ll be much quicker on your table saw. They can be efficient at cutting pockets out of material, but so can a simple jig with a handheld router.
